Hello,
I apologize, as I can only speak english, the backplate will mount easily with the block, just need to use m3.5 x 10, 2x m3.5 x 6, and 2 m3.5 x8 to mount it.
I am trying to attach a few pictures, but am having troubles.
Block mounted on reference GTX570/580 board (this is a 560ti Ultra, but it uses the GTX 580 PCB)
Install as usual, but discard the aquacomputer screws, and also the Heatkiller screws. You will replace with m3.5 x 10 for all but 4 screws
I know it's hard to see, but there are two button head m3.5 x 6 that do not go through the backplate, you can access them right through the two large squares on the backplate.
Thes are the two m3.5 x 8screws for the backplate, I use the nuts that come with the backplate.
I used black socket head screws, in my build, color is a personal preference, also the button heads were my choice, please feel free to use any type of head you want, just remember to use the correct thread size and length.
Hope this helps
